I've had both. They're both great, but different beasts. The N55 sounds much better (deeper, throatier), imo. I do think the N55 gives more of a feeling of starting 'lag' (minor), but has significantly more oomph in most other settings (perhaps that has to do with the DCT, which destroys the Steptronic I previously had). Tuning and mods are still limited for the N55, but are coming.
